Detailed Explanation
How it Works & Explanation
The Body Mass Index (BMI) is a simple measurement that uses a person's height and weight to determine their weight status.
It is calculated by dividing your weight in kilograms by your height in meters squared. BMI does not measure body fat directly, but it is a reliable indicator of healthy weight ranges for most people.
Healthy Tips & Guidelines
- Weigh yourself in the morning before eating or drinking for the most accurate baseline.
- Measure your height without shoes, standing completely straight against a wall.
- Use BMI in conjunction with waist circumference measurements for a better picture of metabolic health.
- Focus on healthy habits rather than obsessing over the exact BMI number.
